I suggest you consider avoiding all sauces and salad dressings to start also. Unless you want to spend hours researching them online. Vitamins and meds can contain gluten also. You need to avoid wheat, rye and barley, and some of us react to oats also. There are lists of bad indgredients on the main site. Spice blends might be a problem so it is safer to stick with single spices rather than mixes.
A few things that I do ok with are: GFCFSFNF list (gluten free, casein free, soy free, nightshade free))
Trader Joe's brown rice tortillas.
Bakery on Main Granola
Food Should Taste Good gluten-free chips
Planters peanuts, but check ingredients
Organic or natural peanut butters.
Hellman's canola oil Cholesterol free mayo.
You might like to try quinoa or teff or amaranth as grain/rice subs.
Basically start simple and build up a list of foods you can eat.
I don't have DH but I think the diet advice is ok anyway.
